Abstract

A lighting system includes a light source, a light redirection element, and a movement mechanism coupled to the light source and the light redirection element. The movement mechanism is configured to simultaneously or stepwise move the light source and the light redirection element between a top lighting position and an interlighting position.

Claims (18)

1. A lighting system, comprising:

a light source;

a light redirection element; and

a movement mechanism coupled to the light source and to the light redirection element, the movement mechanism configured to move the light source and the light redirection element between (i) a first orientation in which the light redirection element is positioned apart from the light source such that light from the light source is emitted in a first emission direction, and (ii) a second orientation in which the light redirection element is positioned near the light source such that light emitted by the light source is emitted in a second emission direction.

2. The lighting system of claim 1 , wherein the movement mechanism is configured to move the light source at a first vertical movement rate and the light redirection element at a second vertical movement rate.

3. The lighting system of claim 1 , wherein the first orientation is a top lighting orientation and the second orientation is an interlighting orientation.

4. The lighting system of claim 1 , wherein the movement mechanism is further configured to move the light source and the light redirection element in a stepwise fashion.

5. The lighting system of claim 1 , the movement mechanism further comprising:

a motor;

a shaft coupled to the motor;

a first wheel coupled to the shaft, the first wheel further coupled to the light source; and

a second wheel coupled to the shaft, the second wheel further coupled to the light redirection element.

6. The lighting system of claim 5 , wherein a diameter of the first wheel is greater than a diameter of the second wheel.

7. The lighting system of claim 2 , wherein the first vertical movement rate is greater than the second vertical movement rate.

8. The lighting system of claim 1 , wherein the light source is at least a first light emitting diode (LED).

9. The lighting system of claim 1 , wherein the light redirection element includes at least one of a reflector and a lens.

10. The lighting system of claim 1 , wherein the light in the first emission direction is directed substantially to a top surface of an object.

11. The lighting system of claim 1 , wherein the light in the second emission direction is directed substantially to a lateral surface of an object.
